Two straight parallel wires, both cárrying 10 A current in the same direction, attract each other with a force of current \( 1 \times 10^{-3} \mathrm{~N} \). If both currents are doubled, the force of attraction will be
(A) \( 1 \times 10^{-3} \mathrm{~N} \)
(B) \( 2 \times 10^{-3} \mathrm{~N} \)
(C) \( 4 \times 10^{-3} \mathrm{~N} \)
(D) \( 0.25 \times 10^{-3} \mathrm{~N} \)
